All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are intended to be within the scope of the present disclosure.
Fig. 3 is a schematic structural diagram of a left-hand turning tool bar with a positive angle for turning. Referring to fig. 3, the turning tool bar comprises a quick-change block 1 and a tool handle 2 detachably mounted with the quick-change block 1.
The quick-change block 1 comprises a cutter head 11 and a first mounting table 12 fixedly connected with the cutter head 11, and the cutter head 11 and the first mounting table 12 form an L-shaped column.
Further, the cutter head 11 is a half round table, a half cylinder or a prism, preferably a half cylinder, specifically, the cutter head 11 is a half round table or a half cylinder obtained by longitudinally cutting along the axial direction of the round table or the cylinder, and includes a planar first reference surface 111, a curved first side surface 112, and a cutter head top surface 113 intersecting with both the first reference surface 111 and the first side surface 112. That is, the tool bit 11 is surrounded by a first reference surface 111, a first side surface 112, and a tool bit top surface 113.
In one possible implementation, the cutting head top surface 113 is angled 75 ° -90 ° from the first reference surface 111.
An insert groove 114 for mounting a turning insert is formed in the cutter head 11 from the first reference surface 111 at a vertex angle formed by the first reference surface 111, the first side surface 112 and the cutter head top surface 113.
In one possible manner, as shown in fig. 13, after the turning blade is mounted in the blade groove 114, the cutting edge for the turning blade forms a principal angle a with the head reference surface 104, the principal angle a being 3 ° to 55 °, and the head reference surface 104 is a plane passing through the tip 103 and perpendicular to the first reference surface 111.
Alternatively, the cutter head 11 is integrally formed with the first mounting table 12, thereby increasing the mechanical strength of the cutter head 11.
Further, the connection between the first reference surface 111 and the first mounting table 12 is provided with an arc chamfer, so that the stress between the tool bit 11 and the first mounting table 12 during cutting is reduced, the tensile strength of the connection is increased, and the service life of the tool bar is prolonged.
Further, a first boss 116 is disposed on the top outer side of the cutter head 11 along the circumferential direction of the first side surface 112, so as to avoid damage to the machined surface caused by the rear end of the cutter bar during the cutting process, i.e. avoid interference.
In one possible manner, a first clearance surface 117 is provided from the top surface 113 of the tool bit to the first mounting table 12, and the first clearance surface 117 passes through the insert pocket 114, so as to reduce unintended contact between a workpiece to be machined and a turning tool bar during cutting machining, thereby reducing a rejection rate.
Specifically, the first clearance surface 117 is formed by combining an inclined surface and an arc surface, and the size and the angle of the inclined surface are selected according to the shape of the turning blade.
Fig. 4 is a bottom view of the quick-change tool holder of fig. 3, and in combination with fig. 4, in one possible manner, a second clearance surface 118 is formed from the first reference surface 111 to the first side surface 112, and the second clearance surface 118 is a plane, so that unexpected contact between the tool holder and a workpiece to be machined in a cutting process is reduced, and a rejection rate is further reduced.
Alternatively, the first mounting table 12 may be a disk, or may be a prism disk. The present inventors have found that if the first mounting base 12 is a disk, the stability of the turning tool bar is enhanced during the cutting process, and therefore, the first mounting base 12 is preferably a disk.
As shown in fig. 3, in one possible manner, the tool shank 2 includes a cylindrical connecting rod 21 for being mounted on a lathe, and a second mounting table 22 for mounting the quick-change block 1 is fixedly connected to one end of the connecting rod 21.
Optionally, the top end of the second mounting table 22 is connected to the bottom end of the first mounting table 12, and the two connected end surfaces are matched.
Specifically, a clamping block 121 protruding outwards is provided on the bottom end surface of the first mounting table 12, and correspondingly, a clamping groove 221 is provided on the top end surface of the second mounting table 22.
Alternatively, a clamping groove 221 may be formed on the bottom end surface of the first mounting table 12, and a clamping block 121 protruding outwards may be formed on the top end surface of the second mounting table 22.
Fig. 5a is a schematic structural view of a tool shank with an "X" type fixture block according to the present embodiment, and fig. 5b is a schematic structural view of a quick-change block matched with the tool shank shown in fig. 5 a. Fig. 6a is a schematic structural view of a tool shank with a "well" shaped clamping block provided in this embodiment, and fig. 6b is a schematic structural view of a quick-change block matched with the tool shank shown in fig. 6 a. The clamping block 121 may be a V-shaped prism, a rectangular prism, an "X" shaped prism or a "well" shaped prism, etc., or may be a spherical boss or other abnormal bosses not shown in the figure. Correspondingly, the clamping groove 221 may be a V-shaped groove, a cuboid groove, an "X" shaped groove, a "well" shaped groove, or the like, or may be a spherical groove or other special-shaped groove. The inventor finds that the clamping block and the corresponding clamping groove with the shapes can apply pressure to the quick-change block 1 and the cutter handle 2 from multiple angles, so that the stability of the turning tool piece in the cutting process is improved, and the cutting rejection rate is reduced.
Further, the depth of the clamping groove 221 is slightly greater than the height of the clamping block 121, so that the clamping block 121 can be stably mounted in the clamping groove 221.
Fig. 7 is a left side view of the arbor of fig. 3, and fig. 8 is an installation view of the arbor of fig. 3. In one possible implementation, as shown in fig. 7 and 8, fixing piece mounting holes 101, 102 for mounting fixing pieces are formed on the quick-change block 1 and the tool shank 2 coaxially, and the fixing pieces are used for fixedly mounting the quick-change block on the second mounting platform 22, and the fixing pieces may be screws or the like.
In one possible implementation, the fastener mounting holes on the top surface 113 of the tool bit and the fastener mounting holes on the first mounting table 12 are symmetrically arranged about a certain diameter of the first mounting table 12, so that the quick-change fastener 1 can be mounted in two directions, and thus on the same turning tool, two adjacent cutting edges of the same turning tool can be used to machine a workpiece.
In one possible implementation manner, the connecting rod 21 includes a second reference surface 211 and a third reference surface 212 that are disposed on the same side of the second mounting table central axis L1 and are parallel to each other, and the distance between the second reference surface 211 and the second mounting table central axis L1 is smaller than the distance between the third reference surface 212 and the second mounting table central axis L1. That is, the connecting rod 21 is not provided at the center of the second mounting table 22, but provided at one side of the second mounting table center axis L1, so that the tool bit 11 and the connecting rod 21 have two positional relationships, and the relative positions of the turning blade and the lathe can be changed by changing the quick-change block, so that the same machining position of the same workpiece can be machined by using two adjacent cutting edges of the same turning blade on the same lathe.
In one implementation, as shown in fig. 3, after the turning blade is mounted in the blade slot 114, the tip 103 of the turning blade is coplanar with the second reference plane 211, and the cutter head 11 and the connecting rod 21 are separated on two sides of the central axis L1 of the second mounting table.
Fig. 9 is a schematic diagram of a positive angle turning tool bar structure for a left-hand lathe according to the present embodiment. The difference from the turning bar shown in fig. 3 is that the quick-change block 1 of the turning bar shown in fig. 9 is chirally symmetrical with the quick-change block 1 of the turning bar shown in fig. 3, specifically, the tool bit 11 and the connecting rod 21 shown in fig. 9 are disposed on the same side of the second mounting platform central axis L1.
With reference to fig. 3 and 9, only the turning tool pieces are required to be mounted on the quick-change blocks which are mirror images (chiral symmetry), and cutting edges on different sides of the same turning tool piece are used in the cutting process, so that the effect that the cutting edges on two sides of the same turning tool piece can be effectively used is achieved.
